The changes to the individual drivers are not large, and a bit of auditing might be necessary because sometimes there are also race conditions involved in setting/clearing the timer. At this point i believe the "one card at a time" approach is the most productive one. A remark is that as time goes on, boxes become faster and faster, and they tend to trigger a lot of performance or timing bugs in the systems with which we have lived happily for ages. cheers luigi ----------------------------------+----------------------------------------- Luigi RIZZO, luigi@iet.unipi.it .
